Nutrients strength and their relationship with soil properties of natural disaster proned coastal soils


Ninety six surface soil samples representing twenty villages of the recently tsunami affected areas of Nagapattinam taluk of Tamilnadu in India were analyzed for the basic soil parameters viz., pH, EC, OC and OM and macronutrients viz., N, P, K by using standard methods. The available micronutrients (DTPA extractable) viz., Fe, Mn, Cu and Zn were investigated by using Atomic Absorption Spectrophotometer (ECIL, AAS-4129). The availability of macro and micronutrients and their relationship with soil properties were also studied. The result showed that the available macronutrients N, P, K was 86.5% low and 13.5% medium for N, 100% low for P and 100% medium for K respectively. Regarding the micronutrients, Fe was found to be sufficient by 97% and Mn deficient by 100%, Zn was found to be sufficient by 53% and Cu deficient by 45% respectively. Further, Fe showed positive correlation with OC but negative correlation with pH. Mn also followed the same trend as that of Fe with OC, EC and pH. Cu showed positive correlation with EC and negative correlation with pH and OC. Zn showed negative correlation with OC and positive correlation with EC and pH.
